The Treaty of Guadalupe Higaldo was signed in the city of Guadalupe Higlado, Mexico on February 2nd, 1848. The treaty brought an official end to the Mexican-American war that was fought from 1846 until the treaty was signed in early 1848. The war initially began when then independent Texas' position of the Rio Grande being the border between Texas and Mexico. When Texas was finally annexed by the United States in 1845, the United States took Texas' position on the border dilemma. The Mexican-American was was subsequently fought over the disagreements in territory and eventually ceased when the Mexican military surrendered in the fall of 1847 as American troops entered Mexico City. For the next year, negotiations were carried out between the United States and Mexico and the Treaty of Guadalupe Higaldo was eventually drafted and signed into effect.



The Effects
When the Treaty was signed into effect, Mexico granted all of their territory in California, New Mexico (which included present day Arizona, and parts of Utah, Colorado, and Nevada. Mexico also officially recognized all of Texas as part of the United States, and in turn recognized the new boundary of the Rio Grande that was previously claimed by Texas. In return, the United States pains about $15 million dollars to the failing Mexican government. When the treaty was ratified by Senate, all of the American troops that were present in Mexico City left and boundary markers were set on the new Mexican-american boundary.

Ties to Sectionalism

When the Treaty was ratified and the United States gained all of the territory ceded by Mexico, controversy soon sparked about whether the territory should be free or be slave territories. The Wilmot Proviso, drawn up by Congressman David Wilmot, granted that all of the new territories of United States ceded from Mexico should be free territories. The Proviso passed the house, but failed in Senate on two occasions. Southerners had a much larger representation in Senate, so the Proviso was shot down very rapidly on both occasions. Although the Wilmot Proviso failed, it lead to national discussions on the matter, and eventually the Compromise of 1850.
